1. General Description
This specification applies to the 42 inch Color TFT-LCD Module T420HW04 V8. This LCD module has
a TFT active matrix type liquid crystal panel 1920x1080 pixels, and diagonal size of 42 inch. This
module supports 1920x1080 Full-HD mode (Non-interlace).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the brightness of the sub-pi xel color is determined with a 8-bit gray scale signal for each
dot.
The T420HW04 V8 has been designed to apply the 8-bit 2 channel LVDS interface method. It is
intended to support displays where high brightness, wide viewing angle, high color saturation, and
high color depth are very important.
T420HW04 V8 Backlight unit used C-balance board (inverter-less) solution. This backlight unit should
bundle integral TV power system to use.

3. Electrical Specification
The T420HW04 V8 requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. The second input, which powers the CCFL, is typically
generated by an power system.

The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced
by the characteristics of the Integrated Power Board (IPB). All the parameters of an IPB should be
carefully designed so as not to produce too much leakage current from high-voltage output of the
IPB. When you design or order the IPB, please make sure unwanted lighting caused by the
mismatch of the lamp and the IPB (no lighting, flicker, etc) never occurs. When you confirm it, the
LCD Assembly should be operated in the same condition as installed in your instrument.
Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to conducting
tape, TFT-LCD Module have a low luminance and the inverter has abnormal action because

The relative humidity must not exceed 80% non-condensing at temperatures of 40 or less. At
temperatures greater than 40, the wet bulb temperature must not exceed 39 . When operate
at low temperatures, the brightness of CCFL will drop and the lifetime of CCFL will be reduced.
